USB and Coaxial at the same time?

@audphile1   Yes it has NOS-OS soft and sharp filers. I like OS/Soft. I think the problem with some older 70's rock is it was engineered to play on boom boxes. Maybe that is a fallacy, I don't know.  NOS seems to shrink soundstage to me. Maybe the magic could be NOS+Coaxial. I will give it a try when I return home from our FL winter this spring.

Cool. Yeah the 70s rock wasn’t recorded to be played thru an accurate hi fi system 

I want to add a little.

Back in the pre-async USB days there seemed to be an argument that coax was a better option to optical because of lower jitter. I think this was due to the quality of the receviers and transmitters, not really a format problem. Coaxial was often preferred except when there were ground loop issues.

Coaxial could be galvanically isolated but wasn’t always, like USB today.

I don’t think there’s any credible argument that coax outperforms async-USB in terms of jitter today. USB of course is the only choice for very high resolution formats and DSD.

I used both coaxial and USB at the same time to test the sound of each on my Aurender N200. I called Aurender and they said it was not designed to use both cables in the unit at the same time. The difference was very slight. NowI only have coaxial connected.

@rvpiano interesting that you prefer coax. Thought you liked that shunyata usb cable
